Bull etf or Bear etf, which one to use? Hi all, If I want to express a bullish view on SP500, I have two theoretically equivalent options (I am thinking of 2x or 3x): 1. Long the bull 3x etf 2. Short the bear 3x etf The holding period is probably 3 months, 6 months and 12 months. Which one shall I hold, the bull or the bear? Thank you!
